Best 2D Game engine

Looking to make a DM-esque platform game.  I was just wondering if there's a freeware indie game engine that you don't have to pay for.  I've already looked at spritecraft, and I tried to use it for a while until I realized it was bullshit in it's complexity; looked at PTK, and was amazed by it's simplicity in comparison.  However, you have to pay for it, like, 200 dollars.  This is a hobbyist game, I don't want to sell it or have to pay to make it. 

So, any response?

Most of the games I play (Kenta Cho's games [http://www.asahi-net.or.jp/~cs8k-cyu/index_e.html] and Hello World Project's games [http://homepage2.nifty.com/isshiki/prog_win_d.html]) are programmed in Digital Mars D using SDL and OpenGL. And their games rock.
